Pretreatment with ticagrelor may offset additional inhibition of platelet and coagulation activation with bivalirudin compared to heparin during primary percutaneous coronary intervention

Background: It remains unknown if bivalirudin compared to heparin confers any additional inhibition of platelet and coagulation activation during primary percutaneous coronary intervention (PPCI) after pretreatment with ticagrelor. Methods: In this substudy of VALIDATE-SWEDEHEART trial, 103 patients pretreated with ticagrelor were randomized before PPCI to heparin or bivalirudin. Blood samples wer

Improving modified differential evolution for fuzzy clustering

Differential evolution is a real value encoded evolutionary algorithm for global optimization. It has gained popularity due to its simplicity and efficiency. Use of special kind of mutation and crossover operators differentiates it from other evolutionary algorithms. In recent times, it has been widely used in different fields of science and engineering. Among recently developed various variants o

Automatic mixed pixel detection using a new hybrid Cellular automata approach on satellite image

Mixed-pixels classification in land-cover regions is a challenging task in remote sensing imagery. To classify mixed-pixels, vagueness is always the main characteristic by handling uncertainty. We propose a hybrid approach for pixel classification using Rough sets and Cellular automata models to solve this problem. Multiple belongingness and vagueness among data can be handled efficiently using Ro

Gene microarray data analysis using parallel point-symmetry-based clustering

Identification of co-expressed genes is the central goal in microarray gene expression analysis. Point-symmetry-based clustering is an important unsupervised learning technique for recognising symmetrical convex- or nonconvex-shaped clusters. To enable fast clustering of large microarray data, we propose a distributed time-efficient scalable approach for point-symmetrybased K-Means algorithm. A na

Remote sensing image classification using fuzzy- pso hybrid approach

Pixel classification among overlapping land cover regions in remote sensing imagery is a challenging task. Detection of uncertainty and vagueness are always key features for classifying mixed pixels. This chapter proposes an approach for pixel classification using hybrid approach of Fuzzy C-Means and Particle Swarm Optimization methods. This new unsupervised algorithm is able to identify clusters

Pichia sorbitophila, an Interspecies Yeast Hybrid, Reveals Early Steps of Genome Resolution After Polyploidization

Polyploidization is an important process in the evolution of eukaryotic genomes, but ensuing molecular mechanisms remain to be clarified. Autopolyploidization or whole-genome duplication events frequently are resolved in resulting lineages by the loss of single genes from most duplicated pairs, causing transient gene dosage imbalance and accelerating speciation through meiotic infertility. Allopol

Evolutionary rough parallel multi-objective optimization algorithm

A hybrid unsupervised learning algorithm, which is termed as Parallel Rough-based Archived Multi-Objective Simulated Annealing (PARAMOSA), is proposed in this article. It comprises a judicious integration of the principles of the rough sets theory and the scalable distributed paradigm with the archived multi-objective simulated annealing approach. While the concept of boundary approximations of ro

PanCareLIFE: The scientific basis for a European project to improve long-term care regarding fertility, ototoxicity and health-related quality of life after cancer occurring among children and adolescents

Aims: Survival after cancer diagnosed during childhood or adolescence continues to improve with new treatments and supportive therapies. Optimal long-term care requires that risks to vulnerable organs are clearly defined and translated into guidelines that are implemented into practice. PanCareLIFE is a pan-European consortium that addresses survivorship issues comprising fertility, hearing impair

Income-related inequality in life-years and quality-adjusted life-years

We estimate the income-related inequality in Sweden with respect to life-years and quality-adjusted life-years (QALYs). We use a large data set from Sweden with over 40,000 individuals followed up for 10-16 years, to estimate the survival and quality-adjusted survival in different income groups. For both life-years and QALYs, we discover inequalities in health favouring the higher income groups. F

On causes and regulation of anti-viral defence in asthma and COPD

Rhinovirus infection is a main trigger of asthma and COPD exacerbations. dsRNA, a viral replication intermediate, is sensed by pattern recognition receptors in the airway epithelium leading to down-stream induction of anti-viral interferons. Several studies have demonstrated that the rhinoviral-induced interferon response can be deficient in asthmatics, possibly resulting in more severe and length

Problem gambling and gaming in elite athletes

Background: High-level sports have been described as a risk situation for mental health problems and substance misuse. This, however, has been sparsely studied for problem gambling, and it is unknown whether problem gaming, corresponding to the tentative diagnosis of internet gaming disorder, may be overrepresented in athletes. This study aimed to study the prevalence and correlates of problem gam

Identification of susceptibility pathways for the role of chromosome 15q25.1 in modifying lung cancer risk

Genome-wide association studies (GWAS) identified the chromosome 15q25.1 locus as a leading susceptibility region for lung cancer. However, the pathogenic pathways, through which susceptibility SNPs within chromosome 15q25.1 affects lung cancer risk, have not been explored. We analyzed three cohorts with GWAS data consisting 42,901 individuals and lung expression quantitative trait loci (eQTL) dat

Effects of acute stress provocation on cortisol levels, zonulin and inflammatory markers in low- and high-stressed men

The virtual version of the Trier Social Stress Test (V-TSST) is an effective and standardized tool for social stress induction. This study aimed to examine gut permeability and physiological and inflammatory markers of reactivity to acute psychosocial stress. Forty young men were classified as high-stressed (HIGHS) or low-stressed (LOWS) according to the Shirom-Melamed Burnout Questionnaire. Cardi

Comparison between patients included in randomized controlled trials of ischemic heart disease and real-world data. A nationwide study

Background: The objective was to compare patients with ischemic heart disease (IHD) undergoing percutaneous coronary intervention (PCI) who were included in randomized controlled trials (RCTs) (trial participants) with patients who were not included (nonparticipants) on a trial-by-trial basis and according to indication for PCI. Methods: In this cohort study, we compared patients with IHD who were

Capability assessments - How to make them useful for decision-making

Capability assessments are becoming increasingly common as part of risk management activities worldwide. Despite this, there is no consensus concerning how these assessments are best conducted and presented. Recent studies suggest that two factors may influence the usefulness of capability assessments for decision-making: namely, whether the assessment includes descriptions of the resources availa
